Embodiment Construction
[0152] Video encoding process such as figure 1 As shown, the intra-frame or inter-frame prediction is performed on the video image first, and the best prediction mode is selected by calculating the cost function in the prediction process, and the residual of the original image and the predicted image is decomposed to obtain the decomposition coefficient matrix, and then the decomposition The coefficient matrix is quantized and entropy encoded to obtain the output code stream, and the quantized coefficients are dequantized at the same time, and the prediction residual block is reconstructed and reconstructed to obtain a reconstructed image, which is used as a reference image for the next frame encoding.
[0153] The decomposition method of the present invention is used to decompose the prediction staggered block to obtain the decomposition coefficient matrix, and its flow is as follows figure 2 shown.
[0154] The reconstruction method of the present invention utilizes the ...
